Can i take and get an accurate pregnancy test 12 days after unprotected sex?

Too soon to test: You should do the test 4-5 days after a missed period. If the result is negative repeat it in 4-5 days. Use first morning urine and follow the instructions carefully. Alternatively you could get a blood test for HCG level a day after the missed period. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine.
